Abstract
Method and system for breaking at least one margin in a glass sheet The invention relates to a method for breaking at least one part to be broken, called a "margin" (12_1, 12_2, 12_3), in a glass sheet (10) bearing at least one cutting line (10_1, 10_2, 10_3) separating said at least one margin from an internal zone (13) of said glass sheet. Said method comprises steps of: - gripping (E10) the glass sheet only in the internal zone, so as to hold the glass sheet in a position in which vibrations are able to propagate on the surface of said internal zone until reaching said at least one cutting line, - vibrating (E20) said internal zone.
